The UROFLOW STOP TEST (UST) aims to highlight the patient's ability to completely hold back the urine, thus giving us an idea of his continence capacity. This concerns the pelvic floor muscles, as well as primarily the sphincter function. This test is performed during a normal Uroflowmetry (UF) test, by merely asking the patient to retain urine after an acoustic signal and then be asked to maintain this "stop" for at least 3 seconds. The stop command was given with a 0.2-second audio signal after about 5 seconds from the beginning of urination. Participants merely responded to the auditory stimuli by interrupting the urine as quickly as possible.
